Nitrogen

Rubber Recycling

Air Products offers a variety of technical services, gas-based solutions and a full line of industrial gases—including nitrogen for small and large volume users. Whether you’re reprocessing crumb rubber or scrap rubber, our applications engineers can work with you to understand your recycling process and implement tailored systems to meet your specific needs. From nitrogen to cryogenic grinding solutions, our offerings can help you grind more efficiently and achieve finer, more uniform particle distribution. Plus, our engineers can recommend improvements that can help you optimise gas use, improve product quality and reduce costs.

Ultra-cold, inert nitrogen can help reduce heat produced in your grinding process, resulting in high-quality, very fine, uniformly sized particles.

Equipment

Cryogenic Grinding Systems

We can provide full systems or component parts, including flow controls, control panels, cooling conveyor and tunnel freezers. Our systems use liquid nitrogen to cool and control the temperature of your product or mill so you can grind more efficiently in an inert atmosphere. They can help you increase production rates, improve product quality, achieve finer particle size and more uniform particle distribution, facilitate difficult material separation and prevent explosion. Our cryogenic specialists can help you determine which system is best for your operation based on your current system, the material you process and your goals.

PolarFit™ Cryogenic Liberation Process

Off-spec parts made from a polymer and a metal contain materials that can be valuable if they are recovered and recycled. Our process offers you an environmentally sustainable way to recover clean components for reuse and recycling. This liberation process uses liquid nitrogen to cool components to extremely low temperatures. At these low temperatures, the polymer portion contracts at a greater rate than the metal portion of the part, creating enough stress to break the bond between the polymer and the metal. This technology can be applied in your separation process to generate a stream of clean metal and a stream of metal-free polymers, making it easier to recover and recycle. Air Products' applications engineers can help you evaluate the use of cryogenic liberation in your processes.
